Yes, they do sit kind of high off the board. The holes would need to be enlarged to make them sit lower - the socket pins have a step in them where the diameter increases that would fit in a larger hole.
Hmm... I think I'll have to offer socket pins as an option. I really don't like the Noval sockets and MillMax pins or something similar would be an alternative. The PCB layout will allow it pretty easily,
